Bosch aquasurf pressure washer

ANSWER : Could be low water pressure I have found.Also, I purchased a can of “stuff” at Lowes today which allows you to circulate a liquid substance which lubricates the pressure pump….the pump could be frozen up…I have a rotating nozzle which I bought…and it had frozen up…this stuff works

ANSWER : If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.

ANSWER : Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.

ANSWER : Id definitley say its over filled. try checking the dipstick

ANSWER : Hi, if it has a chemical injector on the machine then the pressure at the lance will have to be lowered for it to pull in soap. it works on a similar principle to how carburetors on cars pull in fuel, bernouli principle. high pressure at one side of an orifice going to low pressure at the other side which causes a negative pressure ( vacuum) which should pull in the soap. there should be a non return valve at the orifice (hole) which prevents the water back feeding into the soap container, it is quite common for this valve to get stuck, it is just a ball, spring and o ring , and the ball sticks to the o ring. if it is this system then take the soap pick up pipe off the injector and just push the ball off it’s seat with a bit of wire.If it is a high pressure soap system then that is different, but they usually work with an injector in my experience.try taking the high pressure hose off the front off the machine and running it, if it has an injector on it it should pull in plenty off soap.hope this helps ,andy

ANSWER : This happens when the gas needle valve in the carburator sticks open. With it open, gas continues to flow into the carburator then into the cylinder and finally down into the crankcase. It can be caused by dirt in the needle valve’s seat, a stuck needle or float. Most of the time you can remove the float bowl and flush out any dirt. If there’s a lot you should consider flushing the gas tank and check your gas can for dirt. If the washer has been sitting for a long time the problem could be varnish is gumming up the carb works. Carb cleaner works well to flush that out. If the float, needle or seat is damaged you’ll have to rebuild or replace the carb.

ANSWER : Bad pump

ANSWER : Sounds like the problem could be low input water flow or pressure. There could be crud on the intake where you hook up the garden hose, there could be some other sort of blockage. Try hooking it up to the hose and pull the trigger (with the power switched off) and wait to see if water comes out the tip. Also look at the tip(s) themselves. sometimes a piece of crud gets into the hose and then clogs the tip.
